DISH-WASHIN G MACHINE.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed March 18, 1918. Serial No. 223,102.

To all whom it may concern;

Be it known that I, JOHN VAUDREUIL, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee Wisconsin, have'invented certain new and useful Improvements in Dishashing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

y invention refers to fluid 'distributers and the object of the invention is to provide a simple, economical and effective distributer so arranged andv constructed that it will spread a fluid in a maximum area uniformly, while at the same time, the distribution is discharged at various angles.

The invention in this instance is shown in connection with a washing machine, but it is understood that it may be applied to various uses other than that mentioned.

With the above objects in view the invention consists in certain peculiarities of conand the lower portion of struction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently c]aimed. I

In the drawings Figure 1 represents a sectional elevation of a washing machine showing a distributer mounted therein embodying the features of my invention, the section being indicated by .line 11 of Fig. 2, and

Fig. 2 is a sectional plan view of the same, the section being indicated by line 2-2 of Fig. 1.

Referring by characters to the drawings, 1 represents a container or tank having the usual hinged lid and carrying a screen hasket 2 for the reception of dishes, the basket being supported in the upper portion of the container. The container in this instance is in the form of a wheeled truck, as shown, the same forms a well, the center portion of which has extending upwardly therethrough a fluid supply pipe 3-. The end of this fluid supply pipe is provided with a coupling 3 for the reception of a flanged hollow nipple 4' which constitutes a branch of a receiving tube 4. This tube is provided with a counterbalanced blind end 5 and the opposite open end of said tube has fitted thereto a discharge head 6. This head is also provided with a coupling 6 for the reception of a flanged nipple 7 that constitutes part desired speed of a distributing tube 7. The distributing tube 7 is in all respects similar to the receivmg tube just described, except. that it is of smaller dimensions having a blind counterbalanced end and an open discharge end, which latter carries a nipple 8 that is adapted to discharge upwardly at an angle.

As best shown in Fig. 2, the discharge head 6 is also provided with an inclined discharge nipple 6 and the restricted passage through this nipple is regulated by a screw 6. The supply pipe 3 is arranged to be coupled to any suitable source of fluid supply by a hose, not shown, and it carries a controlling valve 9 which has a branch pipe 10 extending therefrom to the upper end of a soap or chemical reservoir 11. The lower end of the reservoir is provided with a valve-controlled lead-pipe 12 which communicates with the main supply pipe 3.

he means shown for supplying soap either in the dry form or 1i uid, forms no part of my present invention, ut is particularly convenient and simplein construction. In its operation, if it is the valve 9 may b as to cause the main supply fluid to 10 and thence through the reservoir and pipe 12 to the distributer. If liquid soap is used and a small sired and, in COIlJllllCtlOIl withthe valve 9,

the soap reservoir may be entirely closed so as to supply a clear rinsing water only.

From the foregoing description it will be observed that the distributor, in general form, has a lanetary movement, that is the receiving tube is caused to revolve at any which is controlled by the jet of fluid exhausted from the nipple 6 and this rotary movement can be increased or decreased by adjusting the screw 6".

As the receiving tube revolves about its axis, it will be observed that the discharge tube revolves similarly upon its axis due to the action of delivered from incline will thus thenipple 8 at an upward constantly change its angle pass through the pipe the fluid and the single jet,

' main receiving tube will have what might of discharge so as to insure cleansin the dishes in the basket above upon all su aces. Attention is directed to the fact that the single jet is thus quite powerful in its force, whereby food particles such as egg and the like adhering to the dishes or vessels are readily removed. This strong ingle spray is maintained even under conditions where the ressure of the fluid is quite low and I consider this an important feature of my invention due to the fact that variation in ,the condition of water supply in difierent localities is a problem which must be met.

It will also be observed, owin to the planetary action of the distributer, that the be termed a more or less intermittent rotary movement whichis caused by therotation of the distributing tube in the same direction, that is, as the discharge nipple of the distributing tube completes a revolution in p the opposite direction from that traveled by the main tube, there will be a slight retardation, which is particularly advantageous in the operation of the device.

The important feature of my invention is the arrangement whereby I have provided a main rotary receiving tube operwashing fluid being discharged in all di-V ating in conjunction with an auxiliary rotary distributing tube mounted upon one of its ends, thus insuring a single jet of the rections upon the surfaces of the articles I the distributing being cleaned.

It is also within-the scope of my invention to invert the receiving arm with relation to the distributing arm in'which case arm would be mounted above the articles to be washed in place of, as shown, being mounted below them.

I claim:

1. A dish washing machine including a casing, means for supporting articles the casing, a vertical supply pipe in the cashig at approximately the vertical axis tributing tube revolubly mounted on the receiving tube adjacent the nozzle, and "a, discharge nozzle on one end portion of the distributing tube adapted to discharge water against articles carried by said supporting means and to rotate the distributmg tube and to also'impart difierential rotative impulses to the receivin tube when the distributing tube is at an adjacent to parallel relation with the receivingtube. 2. A dish washing ma'c 'ine including a casing, means for supporting articles in the casing, a vertical supply pipe in the casin at approximately the vertical axis thereo a receiving tube intermediately w iveled at the supply pipe and communicating therewith, one end of the tube being-61 and provided with a countenbalarpe weight a discharge head at the other en of the tube,

a distri uting tube revolubly d of said distri utthe discharge head, one on communlounted u on,

ing tube being closed and provided, with a counterbalance weight, and a discharge nozzle on one end ing tube adapted to discharge water aga nst articles carried by said Supporting means and to rotate the distrib also impart diifer'ential rotative impulses to the receiving tube when the distributing tube is at and adjacenttoparallel relation with the receivi portion of the distribut-v I ting tube and to so 11% tube. In testimony t at I claim the foregoing I have hereunto set my hand at'Milwaukee in the county of Milwaukee and sea 0%. Wisconsin.
